  <title>Host System Requirements</title>

    <para>Your host system should have the following software with the
    minimum versions indicated. This should not be an issue for most
    modern Linux distributions. Also note that many distributions will
    place software headers into separate packages, often in the form of
    <quote>&lt;package-name&gt;-devel</quote> or
    <quote>&lt;package-name&gt;-dev</quote>. Be sure to install those if
    your distribution provides them.</para>

      <para><emphasis role="strong">Linux Kernel-2.6.x</emphasis>
      (having been compiled with GCC-3.0 or greater)</para>

      <para>The reason for the kernel version requirement is that thread-local
      storage support in Binutils will not be built and the Native POSIX
      Threading Library (NPTL) test suite will segfault if the host's kernel
      isn't at least a 2.6.x version compiled with a 3.0 or later release of
      GCC.</para>

      <para>If the host kernel is either earlier than 2.6.x, or it was not
      compiled using a GCC-3.0 (or later) compiler, you will have to replace
      the kernel with one adhering to the specifications. There are two methods
      you can take to solve this. First, see if your Linux vendor provides a
      2.6 kernel package. If so, you may wish to install it. If your vendor
      doesn't offer a 2.6 kernel package, or you would prefer not to install it,
      then you can compile a 2.6 kernel yourself. Instructions for compiling the
      kernel and configuring the boot loader (assuming the host uses GRUB) are
      located in <xref linkend="chapter-bootable"/>.</para>
